Description

One of the most important tests in light measurement is the assessment of the total radiant power or luminous flux of light sources using integrating spheres. An integrating sphere’s inside surface is coated with a diffusely reflecting material which guarantees complete integration and homogenization of the emitted radiation. The integrated light is then measured at the detector port. A complete series of integrating spheres has been developed by Instrument Systems and is available in a wide range of sizes to provide functionality for a broad spectrum of applications. The maximum dimension of the light source to be measured provides the deciding factor in choosing the appropriate integrating sphere. Larger sources require the use of larger integrating spheres in order to keep measurement errors to a minimum. Instrument Systems integrating spheres all have a side entrance port for determining luminous flux in the 2π configuration (i.e. for determining emission into the forward hemisphere only). With larger integrating spheres, the test object can be mounted in the center, permitting measurements in the 4π configuration (i.e. for determining emission in all directions). • An inner diameter of 75 mm • Can be mounted directly on the base or on an LED Station • LED test space LED-5xx and -6xx • When using in conjunction with an LED sorting machine, the ISP 75 is available with no port flange
